I have heard from several people that you should not eat before going to bed, because the food more easily turns to fat if you don’t “work it off” and just go to sleep!
Is there any truth to me, I do not seem to believe it myself!
I’ve heard this all my life too and I don’t believe it either.
If you are hungry at 11:00 at night, you should eat.
The only thing I’ve heard along those lines is from watching a sumo wrestling documentary where they talked about how they eat. After downing a lot of food they took a nap; supposedly to help them gain/keep the weight. Their bodies certainly reflect that, but that could be due to numerous other causes… one of the big ones being that these guys are already predisposed to bulking up naturally - no one walks in off the street at 120lbs wanting to be a sumo wrestler and is taken seriously.
Heh, my GF tells me I shouldn’t do it but I do.
I normally eat just before going to sleep (around 12 - 1 am) then my next meal is lunch the next day.
I suppose it’s just really bad, but if you eat breakfast as well you’re just packing on the pounds because you’re eating too much.
I lost a lot of weight by not eating before bed. I generally do not eat after 5:30 pm. I don’t know if it works for everyone, and I agree that if you’re hungry at night, you should have a small snack.
Besides, eating late at night can give you some messed-up dreams.
Here is what you get if you google [the most important meal of the day](the Most Important Meal of the Day). The result is link after link after link after link saying the answer is BREAKFAST!
So forget your rationalizations and accept that your GF is right, which doesn’t mean you have to eat breakfast.
This site tells why the GF is right 
[slight hijack] One thing I’ve always wondered is, is the first meal you eat after waking up considered “breakfast,” no matter what time you do so? If so, how much time do you have between waking up and eating before it’s not breakfast anymore? Are certain kinds of foods required for the designation?
I ask because I am a total night person, and sleep in quite a bit when I can. Plus, I don’t really like to eat the vast majority breakfast foods (cereal, toast, pancakes, waffles, etc.), which is actually the main reason why I haven’t eaten breakfast in, literally, years. So I’m curious.

I once heard Dr. Gabe Mirkin talk about this on the radio responding to a caller. he started by saying common sense tells us it cannot be true because “a calorie is a calorie” no matter when you eat it but then he went into an explanation (which I cannot remember and which you may find at his site) which explained why it was true. Food is not processed the same way and while you sleep it is more easily turned into blubber.
In answer to the hijacker: The most complex foods break down in about 8 hours, meaning your body has gotten all the nourishment it can get from past meals. From 8 hours after your last meal you are fasting. When you eat again, you are breaking your fast, or breakfasting. The particular hour has nothing to do with it.
but some people think it does, doesn’t it? calling the first meal you take around noon time brunch.
You need to eat within two hours of waking up. After that, your body kicks into starvation mode.
Your body kicks into “starvation mode” after two hours of not eating in the morning? It might slow down your metabolism, but that you’re actually entering starvation mode sounds a bit unbelievable. Do you have a cite?
Growth Hormone causes you to build muscle. Insulin has an opposite reaction to GH. Eating causes an Insulin response. Which counteracts GH.
All humans release Growth Hormone about an hour and a half after falling asleep. Some other activities cause GH release as well. But sleeping is one of the foremost.
The older you get, the less GH you release. Especially during the day. Bedtime is one of those few times an adult still releases some GH. You are killing one of those few times your adult body releases muscle building GH by eating before bed.
You may have cravings before bed time though because of all kinds of complicated reasons related to Serotonin and its release. Serotonin helps you sleep. Eating causes Serotonin release. So you may think that eating to cause serotonin release is good because it helps you sleep. But what’s really going on is that Serotonin may be depleted for other reasons (most “bad” things cause S release, like eating, smoking, drinking etc). Eating to release Serotonin before bedtime instead of allowing your body to naturally release its serotonin is probably not very good for you.
Forget the name right now but there is a popular supplement people are taking to help get to sleep, not Valerian Root, something else, anyways, they swear it’s “natural” and healthy, but it releases Serotonin to help you get to sleep and my personal feeling is that’s bad too.
All this is just vague recollection from a few books about Serotnonin and GH that I read many years ago. I am not a scientist. So if I’ve made mistakes and you are a scientist, please go easy 
Thanks.
